Tough Shift is a great, scary little pitch on the stacked MF wall. Begin at the right-hand margin of the wall, just right of Graveyard Shift, at a thin jagged crack. The crux is sandbagged, but fairly well-protected, although there is some scary climbing at about 10a.
Climb up the crack into a right-facing corner system and follow this up to an obvious high point that is about 20' below the roof band. Place some high pro and bust it straight left (crux, long reach) to a good, but committing, hold. Take another deep breath and continue left, and then up into a distinctly orange/white shield of rock. The holds are there, but you definitely don't want to blow it as you're looking at a big pendulum whipper. Climb up into the roof and stretch even further left to a welcome flake/jug, and good protection. Pull the roof, and belay at one of the two-bolt anchors above.
The start is tough with thin protection...on a dicey little crack. Then when you get below the roof, there is a nice section that if you come off, you gonna be FLYIN! For maximum fun, pull the roof straight above this last run-out move (make sure you took your biggest piece with you, to stick under the roof (3.5 or 4 Camalot)...this roof brings the grade up to 5.10c or 5.10d (the Dick Williams Gunks Select book says to exit on the easy roof of Graveyard Shift).
I still need to lead this one but will note that Mr. Malloc is right on about the gear. Typically there is gear under such a roof, but somehow it's shallow and wide. My friend barely got a 3 in and said it wouldn't hold and a 4 may be too big. Standing up and reaching over the roof is committing and a fall would be bad news.
